Application filed December 12, 1917. Serial No. 206,805.

To all whom it may concern:

Be it known 4that I, ALBERT Brianna, a citizen of the United States, residing at Millingtor., i-n the county of Tuscola and State of Michigan, have'invented certain new and useful Improvements in Extensible Stovepipes, of which; the following is a speciicastove will be eliminated.

Another and equally important object of the invention is to provide the stove pipe with'novel means for securing the same in adjusted position, thus, preventing undue movement thereof ,and the resultant escape of soot and other dirt therefroi Other objects will be in part obvious'and in part pointed out hereinafter.

The improvemen rangement of parts will be apparent from an inspection of the accompanying. drawings, in connection with the specific description hereinafter contained, and wherein the preferred embodiment of the invention is shown and described -for the purpose of facilitating a full understanding of the same.

In the drawings 2- Figure 1 is a longitudinal section through an adjustable stove pipe having the improved attachment engaged therewi h,

Fig.A 9. is a fragmentary elevation of thel vsame showing parts in section.v

Fig. 3 is a detail in stop. K j

'Having more particular reference to the drawings, in connection with which like reference' characters will designate corre- 'sponding parts, 1 and 2 represent the telescopically engaged tubular sectionspfcthe conventional stove pipe, will be understood. have certain perspective of the be eectually engaged with each other.

Extending lon tudinally of the inner section 1 and secured to the same by rivets ts in the details and ar' which sections,` as' ofthe ends thereof .constricted in order that they'may or like fastening devices is a strip of metal 4 provided with an elongated longitudinally disposed groove, the groove, obviously, ex-

tending for approximately the entire length A plate 6 is slidably arranged on the strip 4 and is apertured to permit the passing cfpbolt- 7 therethrough and through the longls tudinally disposed slot formed washer 8 or like bearing element is arranged over the bolt 7 and upon the strip 4: while a locking nut 9 is turned into engagement with the screw threaded end of said bolt and obviously, serves to clamp the plate 6 to said strip. As will be noted, one end of the plate is bent upwardly to provide an engaging lip 10, which lip is adapted to be engaged, at times, with the adjacent end portion of the outer stove pipe section 1.

In using my improved extensible stove' 1 and 2 are adjusted to the pipe, the sections whereupon the plate 6 1s proper dist-ance adjusted on the strip 4 to a point whereat the adjacent.

the lip 10 ofthe same engages marginal portion of` the outer section. Thus, collapsing or telescoping of the sections will be positively prevented and Vas a consequence, the same will be maintained in proper position when engaged with a iiue or chimney and the draft opening of a furnace or stove. Obviously, other adjustments may be edected by merely loosening and resetting the plate 6 andthe engaging lip 10- formed thereon.

Maniestly, the construction shown is capable of 'considerable modification and such modification as is within the scope of my claim, I consider within the spirit of my invention.

In combination with telescopically engaged pipe sections, a' longitudinally disposed slotted member seured at one end to the inner section, a plate slidable on said member and having. one end of the samebent upwardly to form means for engaging the adjacentend of the outer section, and securing means passing through said plate and the slot in said membe ture hereto.
